And it has been quite rude of the TE to just completely dismiss PJ without even hearing what he had to say. Especially considering he was the director of the superb Braindead.

Why is it rude? The TE owe PJ nothing. As Tolkien himself sold the film rights a long time ago then there is no reason for them to be involved if they don't wish to be. Your post sort of suggests that the TE ought to have been involved simply because PJ directed brain dead which isn't the case. We are not just talking about a book/books that have been turned into a series of films. We are talking about the life's work of his Father and CT, as head of the TE, has every right to refuse to be involved with the films if, in his view, they did not have the necessary respect for the source material. That's his choice. So Frodo Baggins boarded the great ship and passed on into the west till the sweet fragrance on the air filled his sense and the sound of singing came over the water. Then it seemed to him that, as in a dream, he beheld white shores and beyond them a far green country. The third age of Middle Earth was over, the days of the Rings had passed and the story and song of those times was at an end.
